rl.-l=. CHASE COMPENSAIING ENGINE MOUNTING Filed D90. 24, 1928 of a two lobbed cam. That is, it is provided with two diametrically opposite high points. In the drawing` the largest diameter is shown as being on a vertical line, with the periphery lgenerally receding to the opposite low points, ninety degrees from the respective high points. For illustrative purposes, a true circle having the /maximum cam diameter, is inscribed in a dotted line. It will be understood, however, that the degree of recession is somewhat exaggerated in the drawing, the actual range thrufwhich the engine is varied being quite small, in accordance with the low amplitude of inherent engine vibration.

From the above description, it will be seen that as the engine crankshaft rotates, the double lobbed eccentric inner bearing race, imparts to the engine a movement corresponding to and timed with the reaction of the unbalanced moving parts, whereby the inertia thereof is effectively overcome and the supporting frame is relieved of the damaging and disagreeable strains. lllhile the parts and arrangement have been described more orless specitically, it is to be understood that the invention is not to be limited to the exact form shown, but that such obvious modifications may be made as come within the scope of the appended claims.

Having described the invention, I claim:

1. A vibration compensating mounting for bodies having unbalanced operating parts l producing body vibrations, including the combination of a iiXed member, a relatively movable cam member bearing on the fixed member and operated with the movement of said operating parts to impart to the body a movement in synchronism with said body vibrations and an anti-friction element interposed between said members.

2. The combination with a body having moving parts that produce inherent vibration and a supporting frame therefor, of means connecting the frame and body including relatively movable members bearing one on the other, one of which has an irregular bearing surface which upon relative movement of the members varies the position of the body relative to the frame in synchronism with body vibrations, and an anti-friction element disposed between said relatively movable members.

3. The combination with a body having moving parts that produce inherent vibration, and a supporting frame therefor, of a bearing tixedly secured to the frame, and a moving part of said body mounted in said bearing, having an irregular bearing surtare` such irregular bearing surface upon movement of the part causing a relative movement of the body and frame to compensate for the inherent vibration.

el. The combination with a body havingl moving parts causing vibration and a supporting frame therefor. of an anti-'friction .T

bearing carried by the frame, and a moving part projecting from the body and mounted in said bearing, said moving part having an irregular' bearing surface to impart a movement to the body in sym-bronism with said vibration.

5. In an engine mounting, the combination with an engine having a crank shaft and a, supporting frame, of an anti-it'iriction bearing .tixedly secured to the frame, and a rotary cam associated with the engine crank .shaft and mounted in said anti-friction bearing to support the engine and, adapted upon operation of the engine to vary the position ol the engine in relation to the frame to compensate for engine vibration.

G. The con'lbination with a supporting frame and an internal combustion engine supported thereby and having a crank shaft, the moving parts of which engine result in a relative vibration ol the engine in its frame, of a vibration compensating connection between the trame and engine, including, a rotary cam carried by thc engine crank-shaft, having ay pair ot diametrically opposite high points and a pair of low points receding from the respective high points, and an anti-friction bearing for the cam .tixedly carried by the frame, whereby upon engine operation, the engine is given a relative movement with the frame in synehronism with engine vibrations.

7. The combination with an internal combustion engine havingl moving` parts resulting in vibration and a supporting trame therefor, of means comlecting the engine to Vthe `trame and adapted to vary the position of the engine relatively to the frame in svnchronism with engine vibrations, including an eccentric roller artuated by a moving part of the engine, and a bearing therefor tixedlv carried by the frame. i

ln testil'nony whereof l affix my signature.
